HVA 121 EXAM PREP 2026 TEST PAPER
QUESTIONS AND ACCURATE ANSWERS
▶ Intracellular Fluid . Answer: Fluid inside the cell, accounts for 2/3 of body
water
▶ Extracellular Fluid . Answer: Fluid outside the cell, IVF (intravascular fluid
or blood plasma), ISF (interstitial fluid or fluid between tissues and blood),
CSF, and Transcellular fluid (Synovial, Pericardial cavities)
▶ Hydrostatic Pressure . Answer: Push, typically happens at the arterial
level
▶ Osmotic Pressure . Answer: Pull, typically on the veinous level, wherever
the waste needs to be eliminated from the body
▶ Isotonic Solutions . Answer: Completely balanced solutions, blood, NS
▶ Hypotonic Solutions . Answer: Less solute so its less concentrated, only
a few pepper flakes, 0.45% NaCl (1/2 NS)
Give this to dehydrated pt
▶ Hypertonic Solutions . Answer: More solute, so its more concentrated,
lots of pepper flakes, 3.0-5.0% NaCl
Give this to cerebral edema pt
▶ Na+ Normal Range . Answer: 135-145 mEq/L
▶ K+ Normal Range . Answer: 3.5-5.0 mEq/L
▶ Cl- Normal Range . Answer: 98-106 mEq/L
▶ Ca2+ Normal Range . Answer: 8.5-10.5 mEq/L
▶ Mg2+ Normal Range . Answer: 1.4-2.1 mEq/L
▶ Hyponatremia . Answer: Low sodium due to rapid dehydration
